To all whom it may concern Be it known that I, DITRIOH SOHAFER, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in \Vindow- Ventilators, of which the following is a specification.

h/Iy invention relates to ventilators to be applied to the windows of dwellings, etc., and has for its object the provision of a structure by which a thorough ventilation of air may be constantly maintained and at the same time dust, flies, and other insects eX- cluded from the room.

Another object is to provide a device of this character which will allow air to enter a 1'00111 either vertically and indirectly or horizontally and directly, thus preventing or permitting the ingress of a direct current or draft as desired, and which will be inexpensive, simple, durable and efficient, and pleas ing in appearance.

lVith these objects in view, together with the general improvement of the art, my invention consists in the novel construction and arrangement of parts as hereinafter described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a window structure showing my device applied thereto, Fig. 2 is a vertical sectional view therethrough, and Fig. 3 is a horizontal sectional view through one side.

Referring more particularly to the drawings the numeral 1 designates a window structure comprising the side or upright portions 2 formed hollow as is customary for the reception of the sash weights (not shown), and also comprising the usual sill 3.

' The side or upright portions 2 are provided with an outer strip 4 forming the outer guide for the upper sash 5, a parting strip 6 forming the inner guide for the upper sash and the outer guide for the lower sash 7. The usual strip of molding 8 is secured to the sides 2 and contacts with the lower sash for forming the track or runway for the sash. The window structure is also provided with ornamental moldings 9 and 10. The foregoing description is merely of the ordinary type of window and is simply for the purpose of more clearly explaining the attachment and the operation of my device.

My novel ventilating device comprises a housing formed by side plates 11 rigidly Specification of Letters Patent.

Application filed September 24, 1912. Serial No. 722,017.

connected with a base 12 which has its upper surface inclined downwardly toward the outside of the window for a purpose to be described. The device is secured upon the window by means of screws 13 which eXtend through the side plates 11 and into the molding 8. The front of the device comprises a frame 14: hingedly secured at its lower end as at 15 to the bottom or base 12. The lower portion of the frame 14 is covered by a pane of glass 16 and the upper portion 1S covered by wire screen 17. The frame is held in its proper position by hooks 18 secured thereon and engaging eyes 19 secured on the plates 11, thus permitting the frame to be swung downwardly for cleaning the device. In order to prevent water from entering and passing through the hinged connection of the frame with the remainder of the housing during a storm, I provide a strip 20 of any desired material secured upon the base 12 near the hinged connection, as shown.

Secured upon the bottom rail 21 of the lower sash 7 is a frame 22 braced by a bracket 23. The frame 22 is covered with wire screen 24 and is provided at its free end with a strip 25 of rubber or other resilient material.

When the device is placed in position the strip 25 on the frame 22 bears against the glass 16 or the screen 17 depending upon the height to which the sash 7 is raised, thus allowing air to enter and at the same time preventing the ingress of insects.

It will be noted that when the sash 7 is raised so that the strip 25 engages the glass 16 air will pass into the housing and vertically into the room, whereas when the sash 7 is raised so that the strip 25 on the frame 22 engages the wire screen 17 air will pass into the housing and horizontally into the room. By this means it will be apparent that the entry of air can be quickly and easily controlled.

Having thus described my invention what I claim is:

1. A ventilating device for windows, comprising a housing detachably secured to a window frame, said housing comprising a base, side walls, a frame hingedly connected with said housing, a sheet of transparent material disposed in the lower portion of said frame, a screen disposed in the upper portion of said frame, and catches for holding said frame in its closed position, and a screen rigidly secured upon the bottom rail of the lower sash and provided upon its extreme edge with a resilient strip adapted to bear against said transparent material or said first named screen. I

2. A Ventilating device for windows, comprising a housing detachably secured to a window frame and out of the path of travel of the sash, said housing comprising a base, side walls, a vertical frame hingedly connected withsa-id, base and comprising a glass paneinitslower portion and a screen in its upper portion, hooks for holding said frame in its closed position, and a screen secured upon the lower sash rail, extendinginto said housing and resiliently engaging said Vertical frame.

In testimony whereof I hereto affix my signature in the presence of two Witnesses.
